In reply to davidbeynon:
Ha! I did exactly the same as you re. Cristallo - was really good (albeit a long uphill day from Ospitale).
For the Sella - I've done up VF Brigata Tridentina, across plateau to Boe Hutte, sleep there, then down VF Vallon and up VF Piz Da Lech the next day.
The OP - You can do the VF Santnerpass / Kesselkogel / VF Masare as a 2 dayer I'm sure.
You can do some good hut to hut VF in the Brenta too:-
Up Groste cablecar then by path to Tuckett hut, then VF SOSAT to Alimonta hut and sleep there. Next day do either VF Bochette northbound and VF Bernini to Groste, or VF Spellini, Sentier Orsi and VF Benini to Groste (I've done the latter version).
You can do some 2 day stuff in the Triglav region of Slovenia, but any longer than that requires dropping a long way into valleys to link the mountains (no useful cablecars).
There's a nice looking 2 day option around the Coburger hutte / Drachensee in Austria.
One hut-to-hut I really want to do is the Lechtaler Hohenweg -
http://www.lechtaler-hoehenweg.at/ You can do pretty much any distance from 2-10 days depending on where you start and finish.
There's lots of 3+ day hut-to-hut stuff you can do in the alps, the trick is finding an area where you don't drop right down to valley level (unless you want that of course). There are shedloads of VF in the Swiss, Austrian and German alps so don't restrict your view to the Dolomites, the Bergsteigen.com site is a good place to look for VFs (klettersteig).
Re: glaciers - high VF will take you over benign mini glaciers and snow patches which don't have crevasse risk, yet add interest. A set of 6 point crampons will make then much more enjoyable and safe, a rock hard one first thing in the morning is no fun in approach shoes / bendy boots!
